title: Maxillary first molar with aberrant canal configuration: a report of 3 cases.
abstract: The prognosis for endodontic treatment in teeth exhibiting morphological aberrations is unfavorable if the clinician fails to recognize extra root canals. This report demonstrates 3 clinical cases of maxillary first molars that presented 2 canals in the palatal root merging at the apical third (Vertucci's type II canal morphology), a pattern that is rare and seldom encountered.
